What everyone is saying about watching your carbs is very true. Our hospital has a dietician people can make appointments with to discuss special diet plans. She goes over what a proper diabetic diet is -- how much protien, carbs, etc. and also gives out info on how much is in certain foods. Do you have access to something like that?
There are many sample diet plans online to give you an idea of what you should be eating and 100's of recipes out there. A bit of Googling might point you in the right direction.
